I looked alot for documentation. That is what I could not find.
Zinc toxicity is preceeded by common side effects, so it may not be common to see it progress as far as the neuro symptoms.
One does have to be careful with Alternative sites/books. That book Nutritional Healing has good and not so good stuff in it for example. It can get very confusing.
I think the timing of the PolyGrip change in formula is also worrisome. They may have removed the zinc for example(improved taste)...but we will not find evidence of that, since drug companies (especially big ones like GSK) cover themselves really well.
